The fault

How you spot it

On the infotainment of the B9 platform (A4 B9, A5 F5, Q5 FY) the most common complaint is a black screen, a unit that restarts on its own, and a boot that stops partway. A significant part of these are software in origin, not a hardware fault: an update installed at a franchised dealer resolves it.

The buttons of the control interface form a separate branch: a control panel damaged by water ingress or a spilled drink does not respond, and that is a parts replacement. On early cars small electrical faults are common too: intermittent dropouts of the central locking, the parking sensors and the phone connection.

How we know

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
